Just needed a little break in time? Give it a good cleaning and shoot some more . I would shoot a few hundred rounds without cleaning to determine it I would be able to depend on proper functioning. Also,Protrusion of the FP out the bolt face with it bottomed out against the back side of the bolt should be .032 to .037
That would explain the symptoms because the oil would be blown out after a while.
I dont think I oiled it real heavy tho (albeit heavier than many others do)
Something in the firing pin channel is what I was thinking.
I successfully Zeroed my Irons and once i have a Optic on it will zero that was well.
During my next zero process I will get more data points if it was just a blocked channel or break in issue or something else.
Let's see some pics of that bad boy! I love the SP223 lower. My latest build is built on one.

One thing you might not be aware of is that any round that has been chambered in an AR Rifle will and should have a slight indentation in the primer of the round chambered. That is perfectly normal. Also there should not be any break in period on an AR Rifle. They should work out of the box if lubricated properly. Also grease should not be used on them. Only a good quality lubricant like Breakfree, G-96 or other good lube. Rem Oil is not recommended for the AR Rifle. It is great lube for the right weapon or fishing reel but will cook off if the rifle gets hot during shooting a lot of rounds. My main thought was what ammunition are you using? Are the reloads? Also when this occurs is the hammer in the fired position or cocked back? Give us some more details if you can. The Bolt Carrier Group should just look damp. When I put a little lube on the firing pin while cleaning I wipe the lube on and then take a dry patch and wipe off all excess so there is no visible lube on it. Ammunition as previously stated would be my first suspicion on your issue since you advised the bolt is going completely into battery. Try some good quality ammunition like Federal, American Eagle, Winchester, Black Hills for example. Let us know about the hammer position!

Some folks especially gunshop "experts" will clip or bend the hammer springs trying to get a lighter trigger pull. Leads to light strikes.

The problem with being stupid is you cannot simply decide to stop doing dumb things...
-Texas: will do
- Triumph, That is kinda my hope
- Sniper: You'r right I totally forgot about the chambering indent! I did use Hoppes Gun Oil.. I also have EWL and others but i wanted to use up my Hoppes first. I did not wipe the pin after oiling.
I dont think its the Ammo. I made sure for break in i had full powered Federal 5.56 M193
-Jon: Thing is I dont know what the trigger pack is.. when I bought the gun on the strenght on its parts and back story ( shops showroom model) .. I dont know if the trigger back is stock, or a lighter JP spring or what...
-Okdonk, why heavier? ( it currently has a carbine weight) , why not lighter?
